Interaction and immunological effect of very late antigen-4, 5, and fibronectin in tonsillar lymphocytes and their relation to age.


We examined the expressions of alpha-subunits of very late antigen (VLA)-4 (alpha4) and VLA-5 (alpha5) on tonsillar lymphocytes and the interaction between these integrin receptors and their ligand, fibronectin (FN). Immunohistological and flow cytometric analyses showed that alpha4 and alpha5 were expressed in the lymphoid follicle and were positive on… (More)
